Hair plays a prominent role in a person’s overall physical appearance and self-perception. Hair loss has become the most frequent dermatologic concern and people are looking out for ways to enhance their appearance. However, the etiology of hair loss still remains unclear.

“Trichology (the branch of medical and cosmetic study and practice concerned with the hair and scalp) is a rapidly evolving specialty. Keeping abreast with modern research and the clinical applications of evolving knowledge is the pathway to the successful management of dermatological conditions,” said Dr Alka Dogra, a city-based dermatologist

Alopecia is a common dermatological disorder affecting both men and women. However, clinical signs are usually mild and associated with a diffuse thinning of the scalp hair in case of females. It causes serious psychological problems and intense emotional distress, she said.

Other causes of non-scarring hair loss include some hair practices, pulling of the hair (trichotillomania), severe bacterial infections, tinea capitis, and, rarely, abnormalities resulting in fragility or breakage of irregularly shaped hair. Some evidence also suggests an association between hair loss and iron deficiency.

In addition to metabolic and hereditary causes, alopecia is an adverse effect of anticancer, immunosuppressant and many other drug treatments. Drugs used in the treatment of Parkinson’s disease and endometriosis also contribute in hair loss. Antihypertensive medications, particularly B-blocker agents have been reported to cause hair loss occasionally. Several NSAIDs, including celecoxib, diclofenac, etodolac, fenoprofen, indomethacin, kitoprofin, oxaprozin, nabumetone, and sulindac, may also cause loss of hair.

Hypothyroidism or hyperthyroidism may also cause sparse fine hairs or baldness. Pituitary gland injury is also associated with loss of hair. Excess formation of male hormones as a result of any disorder may result in hair fall. Alopecia is also a common cause of hair fall among women. Biological stress is also considered a more common cause of sudden hair fall. Severe psychological stress causes sudden loss of hair. Several mechanical stresses on the scalp and hair could also cause hair fall. The intake of inadequate calories and insufficient protein affect hair growth.

A strict diet to reduce extra weight may contribute to hair loss. Anorexia nervosa may also cause hair fall, she said.
